CONFECTlONERS COOLER.

SPECIFICATION forming part of Letters Patent No. 758,823, dated May 3,1904.

Application filed November 2l, 1903. Serial Nn. 82,114. (No model.)

Be it known that l, GEORGE S. COLLUM, a citizen of the United States,residing' at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inConfectioners Coolers, of which the following' is a specification.

This invention relates to a device for chilling and hardening' hot candyand confections.

The object of this invention is to provide a very simple, cheap. andetiicient water-chilled cooler.

The embodiment of the invention illustrated has two similar flatmetallic plates held apart, so that there is a space between them, bythin packing-strips near the edg'es and secured together by screws, thetop plate having' a polished upper surface and the bottom plate having'openings for the inflow and outflow of water which is circulated betweenthe plates inside of the packingfor carrying off the heat.

Figure l of the accompanying' drawings shows a plan of the cooler with aportion of the top plate broken olf. Fig. 2 shows a longitudinal sectionof the cooler. Fig. 3 shows an end view.

The top plate l and bottom plate 2 are preferably made of steel andsubstantially the same shape, size, and thickness. The upper surface ofthe top plate is made flat and is highly polished to prevent as much aspossible the sticking' of candy or confections to the plate. The bottomplate has openings 3 near one end adapted to be connected by pipes witha water-supply and opening's e near the other end adapted to beconnected with a waste-pipe. Near theiredg'es both plates are drilledand the perforations in the top plate are tapped with threads forreceiving' the screws 5, which are screwed in from the bottom forfastening the plates together. Separating the two plates and formingwaterproofl joints around the edg'es are packing-strips 6. These strips,which may be made of rubber or other suitable packing material, arepreferably halved together at the ends, so as to form a wall of uniformthickness between the edges of the plates. This paclv'ing may be formedof a single strip along each edge or two strips may be used along' eachedge, one lying' outside and one inside of the screws used to fasten theplates together. It is preferred that grooves 7 be made in the innerfaces near the edges of the plates, so that when the plates are drawntogether by the fastening-screws the packing will swell into the groovesand insure water-tight joints. If it is desired, a row of perforationsmaybe drilled through the center of the plates. These perforations inthe top plate are tapped and screws 8 are turned through the bottompla-te into these tapped perforations. Packingwashers 9 are placedaround these screws between the plates in order to prevent lealv'age.These screws prevent the plates from swelling or buckling' at thecenter.

The cooler may be placed on common horses or any convenient support. Hotcandy is poured or hot con fections are placed upon the upper surface ofthe top plate. rater is admittcd under pressure through theinlet-openings at one end of the bottom plate, and after filling thethin space between the two plates flows through the outlet-openings nearthe other end of the bottom plate to the waste. The water is distributedfrom one end to the other, so that the top plate is cooled evenly andthe candy or confections at all localities on it are cooled uniformly.

These plates are very simple to make and easy to fasten together so thatthey will not leak. The top plate may be quickly removed from the bottomplate for the purpose of cleaning', polishing', or adjusting' and iseasily made water-tight when replaced. The rectangular plates may berolled to shape or they maybe cast and the top plate polished in anycommon manner. Butlittle machining' is necessary. fhile both plates arepractically alike, the bottom plate need not be finished as highly asthe top plate.

This cooler occupies but little space, it is light in weight, it iseasily placed upon legs or trestles, it is conveniently handled andtransported, and it is eilicient, although requiring' but a smallquantity of water.

The invention claimed is* 1. A confectionery-cooler consisting' of twoflat metallic plates of uniform thickness arranged parallel with eachother, packing'- stri ps placed near the edges between the plates IOOand holding them slightly separated, means fastening one plate to theother and causing the packing-strips to make water-tight joints with theadjacent surfaces of the plates, and means for the inflow and outflow ofwater whereby a thin iilm of water may be caused to flow between theplates, substantially as specified. f

2. A confectionery-cooler consisting of two fiat metallic plates ofuniform thickness arranged parallel with each other, the bottom platehaving openings near one end adapted to be connected with a water-supplyand openings near the other end adapted -to be connected with awaste-pipe, packingstrips placed near the edges between the plates andholding them slightly separated, and means fastening one plate to theother and causing the packing-strips to make water-tight joints with theadjacent surfaces of the plates, substantially as specified.

3. A confectionery-cooler consisting of two fiat metallic plates ofuniform thickness arranged parallel with each other, packingstripsplaced near the edges between the plates and holding them slightlyseparated, screws extending through perforations in the plates forholding them together and causing the packing-strips to make water-tightjoints with the adjacent surfaces of the plates, and openings for theinflow and outiiow of water whereby a thin film of water may be causedto flow between the plates, substantially as speciiied.

1f. A confectionery-cooler consisting of two fiat metallic plates ofuniform thickness arranged parallel with each other, screws eX- tendingthrough perforations in the plates for holding' them together, andpacking-strips located inside and outside of the screws between theplates and holding them slightly separated and forming water-tightjoints with the adjan cent surfaces of the plates, substantially asspecified.

5. A confectionery-cooler consisting of two flat metallic plates ofuniform thickness arranged parallel with each other, screws eX- tendingthrough perforations in the plates for holding them together near theedges and along the center, and packing-strips located between theplates near the edge screws and about the center screws for holding theplates slightly separated and forming water-tight joints with theadjacent surfaces of the plates, substantially as speciiied.
